Thermal map of fissure system and lava flows

This thermal map shows the fissure system and lava flows as of 12:15 pm on Friday, May 25. Two channelized lava flows are reaching the ocean. In addition, a lava flow is active in Leilani Estates subdivision, near Fissure 7. The region east of the lava channels includes a broad area of recent but inactive lava flows, and this area was not mapped today due to lack of change (see earlier maps for the extent of these flows). The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field.
